Abstract

The invention discloses an organic-inorganic composite flame retardant agent containing a mesopore molecular sieve. The flame retardant agent comprises 0.1-50 weight percent of mesopore molecular sieve and 50-99.9 weight percent of organic flame retardant agent. The preparation method of the flame retardant agent and flame retardant resin containing the flame retardant agent are also disclosed. The composite flame retardant agent obtained through the invention plays roles of both the self-flame retardant function of organic flame retardant molecules and the mesopore molecular sieve and the synergistic effect between the organic flame retardant molecules and the mesopore molecular sieve. The flame retardant efficacy is improved greatly. In addition, the mesopore molecular sieve can also play a releasing role of a microcapsule. As a novel highly efficient halogen-free composite flame retardant agent, the organic-inorganic composite flame retardant agent can be widely applied to the polymer material flame retarding field.

Description

technical field [0001] The invention belongs to the field of macromolecules, and in particular relates to a composite flame retardant containing mesoporous molecular sieve, a preparation method thereof, and a flame-retardant resin containing the flame retardant. Background technique [0002] In recent years, polymers and their alloy materials have been widely used in various fields such as electronics, communication cables, transportation, and construction. However, since most polymer materials are combustible, if flame retardancy is not considered, accidents with large losses such as fires will often be caused. In order to reduce the flammability of polymer materials, prevent fire accidents and reduce economic losses, people pay more and more attention to flame retardant technology. [0003] Generally, adding flame retardants to polymer materials can make them flame retardant. At present, among the flame retardants that have been developed, halogen flame retardants such a...
